My mum's had two straight weeks of radiotherapy on the tumour in her lung and she has started to get severe pains in her chest now, like heartburn. The literature all warns of such pains, along with increasing difficulty in eating, which she is also experiencing. So far, the painkillers don't seem to make much difference.

Anyone got any tips? Remedies? Advice on sleeping positions etc?

She has another five straight weeks of radiotherapy to go (5 days a week) along with chemo once a week. She doesn't handle pain well and she's already threatened to stop all treatment once about a month ago when chemo made her very sick. I have a feeling that if this chest pain gets worse, she'll refuse to have any more radiotherapy. Her choice, of course, but if there's a way of limiting the pain, it would be good to try.
